Or maybe some petrol or carbie cleaner in a spray can???

ALso I'm pretty sure i can buy the replacement filter oil from somewhere like Autobarn yeh???

They only need cleaning every 50,000km, so if you've only done 15,000, save your pennies and wait until it's needed. i check mine every so often, and remove it and give it a shake out if it's looking really dirty.

Just for reference, Ford charge $150+ for the replacement stock filter on the 5.0 SC engines, so a K&N or BMC/KPM is a no brainer really - pays for itself after the first change.
